The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
At present, the problem of insufficient power distribution capacity needs to be overcome when a charging pile is newly added in an airport, the power distribution capacity needs to be increased for an established airport, capacity expansion application needs to be carried out on a power grid transformer substation, and meanwhile, whether the power level of each electric device of the existing power distribution loop supports the newly added power capacity needs to be considered, so that whether distribution equipment such as a distribution transformer, a control switch and a cable needs to be replaced is judged. In addition, airports are limited in space (including above-ground and below-ground) and time, making large-scale power distribution transformation difficult. Various optical fiber cables, cable pipelines, oil pipelines, water supply pipelines, sewage pipelines and the like are laid everywhere underground of the airport. Meanwhile, the normal passage of the flight can be influenced by large-scale reconstruction and construction. Therefore, the upgrading of the distribution capacity on the existing airport has great difficulty, the popularization process of changing oil into electricity of national civil aviation is influenced, more fuel vehicles still exist in the airport, and the development of the green clean environment-friendly airport is hindered.
The inventor researches for a long time and provides a multifunctional combined power supply method for airports, and charging piles are additionally arranged for airports on the premise of not modifying the existing distribution capacity. The inventor obtains the power supply characteristics of airport bridge-mounted equipment on the basis of fully researching and analyzing the ground static variable power supply of an airport airplane, the power supply mode of the air conditioner and the power distribution by testing the actual power test data (the ground air conditioner and the ground power supply consume power under different use conditions for a plurality of times and counting the data of the ground power supply running in the airport for a long time) of the airport field: (1) the aircraft ground static power supply and the air conditioner are intermittently powered, the power supply time in the whole day is positively correlated with the number of flights, and generally the average power supply time in the whole day is about 10 times. (2) According to the statistics of the power supply time of the airplane before, after and after the airplane passes the station, the single power supply time is 1-1.5 hours, and thus the power supply time in the whole day is 10-15 hours. (3) Most airplanes are stopped at 1: 00-6: 00 in the morning at night, and the airplanes do not use the ground static variable power supply and the air conditioner any more in the period of time. (4) The average power actually consumed by the aircraft ground static variable power supply and the bridge-mounted air conditioner is far smaller than the power distributed by the power grid, for example, the power consumption of the A320 aircraft in steady-state operation is within 30KVA, and the power distribution power of the power grid is 90 KVA; the actual average power consumption of the bridge air conditioner is about 130KVA, and the power distribution of the front end power grid is as follows: the single bridge 90 cold tons distributes about 180kVA and the double bridge 110 cold tons distributes about 214kVA, so that there is a large power idle.
According to the conclusion obtained through the research and exploration, the inventor provides the airport multifunctional combined power supply method provided by the embodiment of the invention, and the idle power of the air conditioner power distribution branch and the power supply power distribution branch of the airport is utilized to supply power for the charging pile. The airport multifunctional combined power supply method provided by the embodiment of the invention is applied to a control system, and please refer to fig. 1, which is a schematic view of an application scene of a control system 110. The control system 110 is connected with the air conditioner power distribution branch 210, the power supply power distribution branch 220 and the charging pile 120. The air conditioner power distribution branch 210 and the power supply power distribution branch 220 are commonly connected with a power grid 230, and the voltage of the power grid 230 is generally 380V. The air conditioner power distribution branch 210 is used for supplying power to an aircraft ground air conditioner, and the power supply power distribution branch 220 is used for supplying power to an aircraft ground power supply, for example, supplying power to aircraft lighting.
Referring to fig. 2, the multifunctional combined power supply method for an airport provided by the embodiment of the present invention includes the following steps:
and step S110, acquiring the power of an air conditioner power distribution branch and a power supply power distribution branch.
And step S120, distributing the power of the air conditioner power distribution branch and the power supply power distribution branch to charge the charging pile.
Because the power supply mode of air conditioner distribution branch 210 and power distribution branch 220 is the intermittent type formula power supply, can be when air conditioner distribution branch 210 and/or power distribution branch 220 do not supply power with idle power to filling electric pile 120 power supply, for example when there is not the flight number of shifts, or when stopping a journey late at night, can make full use of this idle period will be surplus electric energy for electric vehicle charges to use daytime conveniently. For example, when the airplane stops at an airport, the air conditioner power distribution branch does not supply power, the power supply power distribution branch distributes the power of the air conditioner power distribution branch to the charging pile when supplying power, under the general condition, when the airplane stays on the airport, the ground power supply can be used, the ground air conditioner can change according to seasons, and the condition that the airplane cannot be used exists, for example, the air conditioner is not used in spring and winter in part of airports. If do not supply power at power distribution branch road again, air conditioner distribution branch road is when the power supply, with the idle power distribution of power distribution branch road to filling electric pile, if again when air conditioner distribution branch road and power distribution branch road all do not supply power, distribute air conditioner distribution branch road and power distribution branch road's power to filling electric pile together.
Or when the power of the air-conditioning power distribution branch 210 and/or the power distribution branch 220 is far less than the power of the power grid, the idle power in the power distribution power of the power grid is distributed to the charging pile 120 for supplying power, for example, when the air-conditioning power distribution branch 210 has idle power and the power distribution branch 220 has no idle power, the idle power of the power distribution branch 210 is distributed to the charging pile 120, and if the power distribution branch 220 has idle power and the air-conditioning power distribution branch 210 has no idle power, the idle power of the power distribution branch 220 is distributed to the charging pile 120, or if both the air-conditioning power distribution branch 210 and the power distribution branch 220 have idle power, the idle power of the air-conditioning power distribution branch 210 and the power distribution branch 220 is distributed to the charging pile 120 together.
Referring to fig. 3, step S120 may include the following sub-steps:
and step S121, acquiring an air conditioner starting and stopping and state signal of the air conditioner power distribution branch, a power supply starting and stopping and state signal of the power supply power distribution branch, a current signal of the air conditioner power distribution branch and a current signal of the power supply power distribution branch.
The air conditioner on/off and status signal can indicate the on/off of the air conditioner in the air conditioner power distribution branch 210 and the running state when the air conditioner is on, such as the power consumption of the air conditioner. The power on/off and status signal can characterize the power on and off of the power distribution branch 220 and the status of operation at the time of the power on, such as the power usage of the power source.
And S122, judging whether the air conditioner power distribution branch and/or the power supply power distribution branch have idle power or not according to the collected various signals. If so, step S123 is performed.
And S123, outputting the idle power of the air conditioner power distribution branch and/or the power supply power distribution branch to the charging pile.
For example, if the acquired air conditioner start/stop and state signal and power supply start/stop and state signal indicate that the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are not enabled, the signal acquisition and logic control module 112 controls the power scheduling module 113 to output the power of the air conditioner power distribution branch 210 and/or the power supply power distribution branch 220 to the charging pile 120, for example, the air conditioner power distribution branch 210 is not enabled, when the power supply power distribution branch 220 is enabled, the power of the air conditioner power distribution branch 210 is output to the charging pile 120, if the air conditioner power distribution branch 210 is enabled, when the power supply power distribution branch 220 is not enabled, the power of the power supply power distribution branch 220 is output to the charging pile 120, or both the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are not enabled, and the powers of the air conditioner power distribution branch 210 and the. It should be noted that the power output to the charging pile 120 may be distributed as required according to the charging requirement of the charging pile 120, or may be directly provided to fully operate the charging pile 120, depending on the actual situation, such as the idle power of the air conditioner power distribution branch 210 and the power supply power distribution branch 220.
In addition, as another situation, if the air conditioner start/stop and state signal and the power supply start/stop and state signal acquired by the signal acquisition and logic control module 112 indicate that the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are enabled, a first difference between the air conditioner power consumption power and the input power of the air conditioner power distribution branch 210 may be calculated according to the acquired current signal of the air conditioner power distribution branch 210, and a second difference between the power supply power consumption power and the input power of the power supply power distribution branch 220 may be calculated according to the current signal of the power supply power distribution branch 220.
When the first difference is greater than the first threshold, the power of the air-conditioning power distribution branch 210 is imported, and the first threshold may be freely set according to an actual situation, for example, in this embodiment, the first threshold may be set to 40KVA, and when the first difference is greater than 40KVA, it is described that the air-conditioning power distribution branch has idle power, and the power supply requirement of the charging pile 120 can be met. When the second difference is greater than the second threshold, the power of the power distribution branch 220 is imported, and similarly, the magnitude of the second threshold can also be freely set. The imported power is output to the charging pile 120, so as to supply power to the charging pile 120, and it is easy to understand that the type of the charging pile 120 can be freely set according to the charging types of the equipment to be charged and the vehicles in the airport, for example, the charging pile can be an alternating current charging pile, and also can be a direct current charging pile.
As a use case, when the charging pile 120 is in use and a start signal of the air-conditioning power distribution branch 210 and/or the power distribution branch 220 is acquired, it indicates that the air-conditioning power distribution branch 210 and/or the power distribution branch 220 need to use the electric energy of the power grid 230, because the ground air conditioner and the power supply have power impact at the start moment, the start power is very high, at this time, the charging pile 120 must avoid the start stage of the ground air conditioner and the power supply, at this time, the control system 110 disconnects the power output to the charging pile 120, so as to avoid affecting the normal use of the air-conditioning power distribution branch 210 and the power distribution branch 220. After the air conditioning power distribution branch 210 and/or the power distribution branch 220 stably operate, it is determined whether the air conditioning power distribution branch 210 and/or the power distribution branch 220 have idle power, and when it is determined that the idle power exists, the idle power is output to the charging pile 120.
Because the charging piles 120 are generally laid in a large number, when the power imported by the control system 110 is small and cannot meet the charging requirements of all the charging piles 120, the control system 110 outputs the imported power to the charging piles 120 with high priority according to the priority of the charging piles 120, and the priority of the charging piles 120 can be set according to the use importance of the electric devices and the vehicles paired with the charging piles 120, which is not limited herein.
In addition, referring to fig. 4, as another embodiment, the control system 110 is further connected to an energy storage system 130. At present, a plurality of airports can encounter the condition of power failure of a ground static power supply, so that airplanes delay or airplane devices are damaged, and complaints of airlines are met. If the ground power supply branch fails to meet the normal operation of the ground power supply due to the power failure of the ground power supply or due to reasons such as power failure of the power grid, abnormal fluctuation of the voltage of the power grid, long-term use aging of electric parts, manual misoperation and the like, the data loss, false alarm faults and the like of the airplane which is being overhauled are caused. Similar problems have been encountered many times in dual-flow airports, Haikou Meilan airports, Zhengzhou Xinzheng airports. In the embodiment of the present invention, the energy storage system 130 is used for storing electric energy, and it is easy to understand that the energy storage system 130 includes an energy storage battery, and the embodiment of the present invention does not limit the type of the energy storage battery, and may be, for example, a lithium iron phosphate battery with a higher density.
The airport combined power supply method provided by the embodiment of the invention further comprises the following steps:
when the power distribution branch circuit is powered off, the power of the energy storage system is output to the power distribution branch circuit; when power distribution branch road and air conditioner distribution branch road do not have idle power or idle power can't satisfy the demand of charging of filling electric pile, judge whether energy storage system's surplus electric quantity can satisfy the demand of charging of filling electric pile, if can satisfy, to filling electric pile output energy storage system's power.
When the power grid is abnormally powered down, the electric energy stored in the energy storage system 130 supplies power to the power distribution branch 220, so that the plane can be ensured to supply power uninterruptedly.
In addition, the control system 110 is further connected to a corridor bridge power distribution branch 240, the corridor bridge power distribution branch 240 is used for supplying power to a corridor bridge of an airport, and the electric equipment of the corridor bridge generally comprises a corridor bridge lifting motor, a rotating motor, a walking motor, an air conditioner, lighting and the like. As long as there is the aircraft to berth, the corridor bridge is in operating condition all the time, and the aircraft stops to berth on the berth after, removes corridor bridge and aircraft and correctly is connected to get on or off the passenger, get on or off the goods in the cargo hold side simultaneously. Generally, when the number of the cargos is small and all the passengers get off, the weight of the airplane becomes light, the airplane can be lifted upwards at the moment, and meanwhile, the corridor bridge also needs to be lifted correspondingly. And the ground clearance of the airplane is lowered when the whole airplane is heavier, and the gallery bridge is lowered correspondingly. If the bridge is powered down when the aircraft ascends or descends, and does not move up and down correspondingly with the aircraft, the shell of the aircraft can be scraped. In addition, for the corridor bridge airplane position, after the airplane enters the port and stops on the airplane position, the corridor bridge is operated manually and electrically to abut against the airplane so as to enable passengers to get off the airplane. If the corridor bridge is powered off at the moment, the corridor bridge cannot be close to the airplane in time, and the corridor bridge can only be dragged and moved manually or replaced by a movable ladder car. Meanwhile, when the airplane leaves the port, the corridor bridge needs to be quickly evacuated, and the airplane slides out of the airplane position. If the corridor bridge is powered off at the moment, the corridor bridge can be manually dragged to evacuate the airplane. No matter the airplane is in or out of port, when the corridor bridge power supply system is powered off, passengers can be delayed from getting on or off the airplane, and thus flights are delayed; on the other hand brings very big trouble for ground equipment operation service personnel, needs more personnel to carry out the pulling of shelter bridge and seeks the portable ladder-driven car of replacement. When the corridor bridge power distribution branch 240 loses power, the method provided by the embodiment of the invention further comprises the following steps: and outputting the power of the energy storage system to the corridor bridge power distribution branch.
The method provided by the embodiment of the invention can ensure that the corridor bridge can work normally, and it should be noted that, in the embodiment of the invention, when the energy storage system 130 supplies power to the corridor bridge power distribution branch 240, the on-off of the circuit can adopt a manual operation mode in consideration of the power supply safety problem of the corridor bridge. In other embodiments, an auto-close mode may be used. In addition, in order to facilitate the removal of the gallery bridge or solve the problem of gallery bridge frequency modulation, the ground air conditioner and the power supply need to be evacuated from the gallery bridge when the gallery bridge is moved.
The airport multifunctional combined power supply method provided by the embodiment of the invention utilizes the idle power of the air conditioner power distribution branch and the power supply power distribution branch of the airport, and the charging pile equipment is equipped for the airport on the premise of not increasing the power of a power grid and power distribution facilities, so that the problem of difficulty in charging electric vehicles in the airport is solved, and the idle power of the airplane ground static power supply and the air conditioner in the airport is fully utilized.
Fig. 5 is a system block diagram of the control system 110 according to the embodiment of the present invention.
The control system 110 includes a power bus module 111, a signal acquisition and logic control module 112, and a power scheduling module 113. In the embodiment of the present invention, the power converging module 111 may be configured to perform the step S110, and the signal collecting and logic control module 112 and the power scheduling module 113 may be configured to perform the step S120.
The power bus module 111 is electrically connected to the air conditioner power distribution branch 210 and the power supply power distribution branch 220. The power combiner module 111 is used for combining the power of the air conditioner power distribution branch 210 and the power supply power distribution branch 220. The power combining module 111 described in this embodiment controls the power of the air conditioner power distribution branch 210 and the power supply power distribution branch 220 to be input and output through the on-off of the circuit breaker, it is easy to understand that both the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are ac power, the power combining module 111 may include an ac circuit breaker, for example, an ac circuit breaker including a circuit breaker, an electromagnetic coil, and an auxiliary alarm contact, wherein the circuit breaker may be a circuit breaker of type T3N 2503P 160a 690VAC of ABB (asae Brown boveri), the electromagnetic coil may be an electromagnetic coil of type YO-C10 a 220VAC/DC of ABB, the auxiliary alarm contact may be an auxiliary alarm contact of type AUX-C3Q +1SY 250V of ABB, and the type and the kind of the circuit breaker are not limited in the embodiment of the present invention.
The signal collection and logic control module 112 is configured to collect an air conditioner start-stop and state signal of the air conditioner power distribution branch 210, a power supply start-stop and state signal of the power supply power distribution branch 220, a current signal of the air conditioner power distribution branch 210, and a current signal of the power supply power distribution branch 220. And judging whether the air conditioner power distribution branch 210 and/or the power supply power distribution branch 220 have idle power or not according to the collected various signals. The air conditioner on/off and status signal can indicate the on/off of the air conditioner in the air conditioner power distribution branch 210 and the running state when the air conditioner is on, such as the power consumption of the air conditioner. The power on/off and status signal can characterize the power on and off of the power distribution branch 220 and the status of operation at the time of the power on, such as the power usage of the power source. The signal collection and logic control module 112 may analyze whether the air-conditioning power distribution branch 210 and/or the power distribution branch 220 have idle power according to the air-conditioning start-stop and state signal of the air-conditioning power distribution branch 210, the power start-stop and state signal of the power distribution branch 220, the current signal of the air-conditioning power distribution branch 210, and the current signal of the power distribution branch 220.
The power scheduling module 113 is electrically connected to the charging pile 120, and when the signal acquisition and logic control module 112 determines that the air-conditioning power distribution branch 210 and/or the power distribution branch 220 have idle power, the signal acquisition and logic control module 112 controls the power scheduling module 113 to output the idle power of the air-conditioning power distribution branch 210 and/or the power distribution branch 220 to the charging pile 120.
For example, if the air conditioner start/stop and state signal and the power supply start/stop and state signal acquired by the signal acquisition and logic control module 112 indicate that the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are not enabled, the signal acquisition and logic control module 112 controls the power scheduling module 113 to output the power of the air conditioner power distribution branch 210 and/or the power supply power distribution branch 220 to the charging pile 120, for example, the air conditioner power distribution branch 210 is not enabled, when the power supply power distribution branch 220 is enabled, the power of the air conditioner power distribution branch 210 is output to the charging pile 120, and if the air conditioner power distribution branch 210 is enabled, the power supply power distribution branch 220 is not enabled, the power of the power supply power distribution branch 220 is output to the charging pile 120, or both the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are not enabled, and the powers of the air conditioner power distribution branch. It should be noted that the power output to the charging pile 120 may be distributed as required according to the charging requirement of the charging pile 120, or may be directly provided to fully operate the charging pile 120, depending on the actual situation, such as the idle power of the air conditioner power distribution branch 210 and the power supply power distribution branch 220.
In addition, as another situation, if the air conditioner start/stop and state signal and the power supply start/stop and state signal acquired by the signal acquisition and logic control module 112 indicate that the air conditioner power distribution branch 210 and the power supply power distribution branch 220 are enabled, the signal acquisition and logic control module 112 may calculate a first difference between the air conditioner power consumption power and the input power of the air conditioner power distribution branch 210 according to the acquired current signal of the air conditioner power distribution branch 210 and calculate a second difference between the power supply power consumption power and the input power of the power supply power distribution branch 220 according to the current signal of the power supply power distribution branch 220.
When the first difference is greater than the first threshold, the signal collection and logic control module 112 controls the power of the power convergence module 111 to be converged into the air-conditioning power distribution branch 210, where the first threshold may be freely set according to an actual situation, for example, in this embodiment, the first threshold may be set to 40KVA, and when the first difference is greater than 40KVA, it is determined that the air-conditioning power distribution branch has idle power, and the power supply requirement of the charging pile 120 can be met. When the second difference is greater than the second threshold, the signal collection and logic control module 112 controls the power of the power converging module 111 to be converged into the power distribution branch 220. The signal acquisition and logic control module 112 controls the power scheduling module 113 to output the power converged by the power convergence module 111 to the charging pile 120, so as to supply power to the charging pile 120, and it is easy to understand that the type of the charging pile 120 can be freely set according to the charging types of the equipment to be charged and the vehicles in the airport, for example, the charging pile can be an ac charging pile, and also can be a dc charging pile.
As a use case, when the charging pile 120 is in use, the signal collection and logic control module 112 collects a start signal of the air-conditioning power distribution branch 210 and/or the power distribution branch 220, which indicates that the air-conditioning power distribution branch 210 and/or the power distribution branch 220 need to use the electric energy of the power grid 230, because the ground air conditioner and the power supply have power impact at the start moment, the start power is very high, at this time, the charging pile 120 must avoid the start stage of the ground air conditioner and the power supply, and the signal collection and logic control module 112 controls the power scheduling module 113 to disconnect the power output to the charging pile 120, so as to avoid affecting the normal use of the air-conditioning power distribution branch 210 and the power distribution branch 220. After the air conditioning power distribution branch 210 and/or the power distribution branch 220 stably operate, the signal acquisition and logic control module 112 determines whether the air conditioning power distribution branch 210 and/or the power distribution branch 220 has idle power, and when determining that the idle power exists, controls the power scheduling module 113 to output the idle power to the charging pile 120.
In the present embodiment, the signal collection and logic control module 112 may complete logic operations and operations through various processor chips, for example, the processor chip may be CP L D (Complex Programmable logic Device) and FPGA (Field Programmable Gate Array), according to the use importance of the electric devices and vehicles paired with the charging pile 120, where the processor chip may be CP L D (Complex Programmable L analog Device).

When the power distribution branch 220 is powered off, the signal acquisition and logic control module 112 controls the power scheduling module 113 to output the power of the energy storage system 130 to the power distribution branch 220. When the power grid is abnormally powered down, the electric energy stored in the energy storage system 130 supplies power to the power distribution branch 220, so that the plane can be ensured to supply power uninterruptedly. In addition, when the power distribution branch 220 and the air conditioner distribution branch 210 do not have idle power or the idle power cannot meet the charging requirement of the charging pile 120, the signal acquisition and logic control module 112 determines whether the remaining capacity of the energy storage system 130 can meet the charging requirement of the charging pile 120, and if so, the signal acquisition and logic control module 112 controls the power scheduling module 113 to output the power of the energy storage system 130 to the charging pile 120. The energy storage system 130 is arranged to provide electric energy for the charging pile 120 when the power distribution branch 220 and the air conditioner distribution branch 210 do not have the capacity to meet the charging requirement of the charging pile 120.

When the energy of the energy storage system 130 is insufficient and the air-conditioning power distribution branch 210 and/or the power distribution branch 220 have idle power to supply to the energy storage system 130, the DC/DC module 116 charges the energy storage system 130, for example, when the signal collection and logic control module 112 determines that the power scheduling module 113 schedules power to the charging pile 120, the air-conditioning power distribution branch 210 and/or the power distribution branch 220 still have idle power and the electric quantity of the energy storage system 130 is not full, and the signal collection and logic control module 112 controls the DC/DC module 116 to charge the energy storage system 130.
